Coleman A/C Issues

I've replaced both the run capacitor and fan capacitor on my ac unit. The fan starts but I do not think the compressor or condenser is running. The air coming out doe snot get colder. If I switch to fan it stays same and if switch back to cool on thermostat I then get nothing and have to wait and fan will eventually start. I jumped the relay which I believe is start relay on the board. put the black and purple together and I can hear and feel vibration from condenser. and it will do this at the minute the breaker is turned on regardless of thermostat position. One put back together through relay I have nothing again. same difference shore power or with generator. Both used to power it up without issue before. Any other thoughts..? help..?
